- heat of the producer, the grit produced, and

the location of the driving mechanisms heretofore utilized, effective lubrication has been found to constitute a considerable problem. It is also necessary to rotatethe grate at a considerably lower speed than the cover. By the present invention there is provided an efliciently lubricated driving mechanism in which the motor is so located as to be readily accessible and in which the base is driven from a portion of the cover driving mechanism operating at a reduced speed.

In the accompanying drawings there is shown, for purposes of illustration only, a preferred embodiment of the present invention, it being understood that the drawings do not define the limits of the invention, as changes in the construction and operation disclosed therein may be made without departing from the spirit of the invention or scope of my broader claims.

In the drawings:

Figure 1 is a vertical sectional view through one form of gas producer embodying the present invention;

Figure 2 is a top plan View, on an enlarged scale, illustrating a portion of the driving mechanism, and

Figure 3 is aside elevation, partly in section and partly broken away. of a slightly Ironodified form of driving mechanism for the ase.

In carrying out the present invention, there may be provided a gas producer body 2 of any usual or standard construction having a cover 3 rotatably supported thereon and an ashpan 4 carrying a grate 5 and mounted for rotation relatively to the body.

The cover is preferably of the type having on its periphery a plurality of teeth 6. Engaging with these teeth for rotating the cover is a spur gear or pinion 7 splined to a short vertical shaft 8. For driving the vertical shaft there is provided a secondary driver 9 preferably in the form of a worm wheel adapted to be driven by the worm 10 secured to the horizontally extending shaft 11. The shaft 11 has secured on one end thereof a gear 12 with which meshes a smaller gear 13 on a second horizontally extending shaft 14:. On

the other end of this second shaft there is secured a gear 15 with which meshes a pinion l6 onthearmature shaft of the motor 17, the

motor constituting the primary driver.

The shafts 8, 11 and 14 are preferably car'- ried by bearings formed in a housing 18 withducing means forthe shaft 11 is utilized in rotating theashpan 4. This may be accomplished by securingto one end of the shaft 11 acrank oreccentric 19 adapted to cooperate with one end'of a pitman 20, the lower end of which cooperates with a lever 21 having an oscillating movement about the axis of a shaft 22. This shaft 22 is journaledin a housing 23 similar in many respects to the housing 18, and carries a Worm 2d meshing with a seconddary driver in the form of a worm wheel 25 .carried'by the vertical shaft26. This shaft alsohassecured thereto a spur gear or pinion 27 meshingwith the annular gear 28 secured to the ashpan 4:. The lever 21 preferably carries a pivotally mounted pawl 29 engaging the teeth on the ratchet wheel secured to the shaft 22. a

With the construction described, it will be apparent that each rotation of theshaft 11 will be effective for moving the pitman 20 through a complete cycle, thereby moving the ratchet wheel and its associated parts through 'a distance. determined by the angular move- Inent of the lever 21. In order to make the the driving mechanism is proamount of this movement adjustable, the lever 21 is preferably provided with a series of openings 31 with which the pitman may be operatively connected. As the point of connection between the pitman and the lever is moved outwardly from the shaft 22, the amount of movement imparted to the shaft will be lessened, as well understood.

In Figure 3 there is illustrated a slightly modified embodiment of the invention, in. which parts corresponding to the parts heretofore referred to in detail are designated by the same reference characters having a prime afliXed thereto. invention, the lower end of the pitman 20 is pivotally connected to a crosshead 32 which is adjustable along the lever 21 by means of the feed screw 33.

The housing 23, like the housing 18, is adapted to contain a supply of lubricant. Each of these housings and its associated parts represents a complete driving unit which may be bodily removed or replaced, as found necessary. The upper housing, together with the motor 17 is substantially in the planev of the cover 3, thereby rendering it very accessible and bringing it in a zone which is relatively cooler and free from the heavier particles of grit.

The advantages of the present invention arise from the provision of an improved driving means for both the cover and base of a producer.

Further advantages arise from the method of driving the driving mechanism for the ashpan and grate from a portion of thevdriving mechanism for the cover, which operates at a speed relatively slow as compared to that of the motor speed. 1
